Tire tread



FIG. 1 is a side perspective view of a tire tread showing our new design, it being understood that the tread pattern is repeated throughout the circumference of the tire tread, the opposite side being the same as that shown;

FIG. 2 is a front elevational view thereof, the opposite side being identical thereto;

FIG. 3 is a side elevational view of the right side thereof;

FIG. 4 is side elevational view of the left side thereof; and,

In the drawings, the broken lines defining the sidewall, inner bead and the peripheral boundary between the claimed tire tread and the unclaimed sidewall depict environmental subject matter that forms no part of the claimed design.
